Purchase this pool cover in September and noticed in March that I had ripped and let it all that junk in my pool. Tried contacting the company with their phone number that was supplied with cover and all you can do is leave a message they never call you back I've called 10 times even tried finding an email address for the company and they still don't answer. Waste of money!

Great cover and great price, has held up two seasons thus far. We get alot of snow and rain and it has held up very well with the heavy top weight. Looks good, has retained its color.

I have a 14 foot pool so I bought this and it did exactly what it was supposed to but next year I will be buying the next size up and using some sand bags. With the snow and rain weighing it down I wish I had more material around the pool preventing excess water and sun light to enter the pool.

We ordered the 15 ft cover the first time and it didn’t fit our 15ft pool, we returned it and bought this 18 ft cover. It’s huge but does the job. The cable didn’t last the winter. A large wind storm snapped the cable in half.

Ya había comprado una de esta marca en otra medida y me salio excelente pero esta se rasgo al momento de ponerla en la primera vez, aun funciona pero se siente más delgada qué la anterior siendo de la misma marca, el cabestrante de esta también funciona deficientemente

I recently had the misfortune of purchasing the Winter Block WC18R Aboveground Pool Winter Cover, and I can confidently say it's been a complete disaster from day one. This so-called "winter cover" is more like a recipe for frustration and disappointment. Here's a scathing review of my dreadful experience:1. Poor Quality Materials: The quality of this cover is shockingly low. It feels as though it's made from the flimsiest material available, more akin to a trash bag than something that should protect your pool throughout the winter.2. Inadequate Size: Despite being advertised as an 18-foot cover, it barely covers my 16-foot aboveground pool. It's like trying to fit a square peg into a round hole, and the edges flap around like a loose flag in the wind.3. Weak Construction: The stitching and overall construction of the cover are abysmal. It's like they used dental floss to hold it together. I had to reinforce several seams to prevent the cover from falling apart.4. Useless Tie-Downs: The included tie-downs are an exercise in futility. They snap, break, or come undone with even the slightest breeze. It's like trying to secure your cover with wet spaghetti – utterly useless.5. Poor Drainage Design: The design of this cover makes it sag in the middle, creating a water pool instead of preventing it. It's like a rainwater reservoir that threatens to collapse under the weight, potentially damaging your pool.6. Total Lack of Durability: If you expect this cover to withstand the harsh winter elements, think again. It's more likely to give in to the first gust of wind or snowfall. It's like having a paper umbrella in a hurricane.7. Misleading Advertising: The product description and images are misleading at best. What you see is not what you get, and you end up with a flimsy, ill-fitting, and practically useless piece of pool cover.8. Wasted Money: This cover is not only a waste of money but also a waste of time and effort. I had to spend extra on a better cover to actually protect my pool from the winter weather.In conclusion, the Winter Block WC18R Aboveground Pool Winter Cover is an absolute disaster. Its poor quality, inadequate size, weak construction, and useless tie-downs make it a terrible investment. Instead of protecting your pool from the winter, it's more likely to cause you headaches and additional expenses. I strongly advise against purchasing this cover and suggest looking for a more reliable option that won't leave you regretting your choice.
